Sharp X68000

Early machines use the rare Shugart Associates System Interface (SASI) for the hard disk interface; later versions adopted the industry-standard Small Computer System Interface (SCSI). If a X68000 user restricts himself to use only filenames according to the 8.3 characters scheme of DOS, using only Latin upper case characters, then a disk written on the X68000 is fully compatible with other Japanese standard platforms like e.g. the NEC PC-9800, the Fujitsu FMR and FM Towns computers. Capcom produced a converter that was originally sold packaged with the X68000 version of Street Fighter II′ that allowed users to plug in a Super Famicom or Mega Drive controller into the system.
